Abstract

High temperatures lead to oxidative stress which can decrease the quality of spermatozoa. Watermelon’s rind have an ability for antioxidants effect that can reduce sperm’s damages that results by role explanation of free radicals. This study aimed to determine the effect of extract of watermelon’s rind on the motility and viability of sperm on male rat exposed to heat. This experiments use rat as animals experiment with five treatments and four repetitions. Five treatments are: P0: without exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P1: was exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P2: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 20 mg/rat/day, P3: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 40 mg/rat/day, and P4: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 80 mg/rat/day. The treatment was done for 52 days. The results, P4 have the best effect that can be increase the motility and viability of rat’s sperm (Rattus norvegicus) exposed to heat.

Abstract

The purpose of this research was to know the relationship between age with calving inteval (CI), days open (DO), and service per conception (S/C) in Friesian Holstein dairy cattle (FH). The research was started on Desember 2017 to January 2018 in PT. Greenfields Indonesia partnerships, KecamatanWagir Kabupaten Malang. The materials of the search used were 100 heads of dairy cattle which had at least two times of parturition. The method used in this research was a survey and data collection. The data were obtained from the records of reproduction. Data analysis was multiple linear regression using SPSS software 21.0 version. The results showed that the values of CI (434,9±58,9 days, 449,4±66,2 days, and 431,8±59,2 days), DO (218,9±58,7 days, 218,9±58,7 days, dan 217,6±54,1 days), dan S/C (3,2±1,8 times, 4,3±1,9 times, 2,6±1,1 times) for the ages of 4, 5, 6. The relationship between age with CI and DO were not significant (P>0,05), but the relationship between age with S/C was significant (P<0,05). The value of S/C increased on dairy cattle at age of 4 to 5 years and started to decreased at the age of 6 years.
